ROLL-HEATING DEVICE.

Specification of Letters Patent. Patented June 15, 1920.

Application filed June 19, 1919. Serial No. 305.275.

To all whom it may concern:

Be it known thatI, ANsoN S. RICE, a citizen of the United States, and a resident of the city of New York, borough of Brooklyn, county of Kings, and State ofNew York, have invented a new and Improved Roll- Heating Device, of which the following is a full, clear, and exact description.

The present invention relates to. new and useful improvements in roll-warming devices, and pertains more particularly to. de vices of this character especially adapted for heating or warming rolls in large quantities for use in hotels, restaurants, and the like.

The primary object of the invention is to provide a device of this character in which the heat supplied thereto is furnished bya heater'of the electric type.

A further obj ect of the invention is to construct a device of this character in such a manner that the heated interior is automatically provided with the necessary amount of moisture to. prevent drying out of the rolls during the heating operation. V

A still further objectof the invention is to provide means for automatically controlling the moisture within the receptacle;

VVith'the above andother objects in view, reference is had to the accompanying drawings in which- 1 Figure 1 is a front elevation ofthe device in the closed position;

Fig. 2 is a vertical sectional view thereof; F 3 is'a similar view taken in a plane at right angles to Fig. 2; p

Fig. 4 is a vertical sectional view on the line 1 1 of Fig. 2;

Fig. 5 is a vertical sectional view taken in a plane at right angles to Fig. 41;

Fig. 6 is a detail view of the moistening ings, the reference character 10 designates a suitable receptacle, the front 11' of which is open and is adapted to be closed by means of a vertically sliding door 12 anda pivoted door 13. The receptacle 10 is supported on a suitable frame 14-, the vertical legs of which are braced by means of ashelf 15 and braces 15.

Mounted within the receptacle 10 is a plurality of anglebars 16, which are adapted to form the means by which wire baskets or the like 17 are carried; These angle bars'16 are secured to vertically extending angle bars 18, and said angle bars are spaced from the side walls of the receptacle, as best shown in Fig. 3. Mounted in thebottom of the receptacle is a falsebottom 19,'which provides means forcleaning the bottom of the receptacle by removing said false bottom19f w l T I As above stated, the doors 12 and 13are of the vertically sliding pivoted type, respectively, and pivotally secured as tree, to thelower edge of thedoor 12, is a link 21 "Pivoted to the link 21,. is a lever 22, which is pivoted at itsrear end as at 23. Project ing from the lever 22 in a plane atright angles to the main body thereof, is a crank arm 24, andpivotally secured as at'25, to said crank arm 24L, is a lever 26, the forward end of which is pivoted as at 27, to the inner face of the door 13, whichin turn is pivoted asat28.

Pivoted to the lever 22, as at 29, is a downwardly extending lever 30, and pivotally connected as at 31, to the lower end of the lever 30, is a lever 32. The lever 32' is pivoted as at 33, to the bottom braces'15,as best seen in Fig. 2.

It is to be understood that the lever mechanism above mentioned, is duplicated on the opposite side of the machine as shown in Fig. 3.

By this construction it willbe seen'that as the forward end 34of the lever 32 is depressed, the several levers 21, 22, 24, 26. and 30 will be operated to-slide thedoor 12 and rock the door 13 to open the device. After pressure has been relieved on theforward end of the lever 34, the same'returns'to its normal position under the influence of the weight of the reciprocating door '12, and

' serves to close said door 12, together with the door 13. A dashpot 35 is employed to .retard the closing movement :of the doors, and eliminate the closing actlon.

is provided with a suitable switch 38 for controlling circuits in the heaters 36. Leading from the rear of the box 37, is a conduit 39, which extends beneath the receptacle 10 to an outlet box 40, as is best seen in Fig. 2.

Mounted above one of the heaters 36, is a pan 41., and leading to one end of said pan 41, is a supply pipe 42, the discharge pipe for said pan being located at the opposite end and designated by the reference character 43. Mounted in the bottom of the pan 41, is an absorbent pad 44, the purpose of which will be hereinafter more fully defined.

Mounted within the receptacle 10 is a water tank 45, and adapted to supply water to said tank 45, is a pipe line 46, which communicates with a Valve 47 more clearly shown in Fig. 4. This valve is automatically opened and closed by means of a float 48, which is pivotally mounted as at 49, and in its pivotal action serves to reciprocate the valve 50 to permit of a flow of water through the pasage 51. Leading from the tank 45, is a drain 52, and said drain communicates with a chamber 53, in which is mounted a valve stem 54, the lower end of which is adapted to coact with the valve seat 55 to prevent a flow of water from the chamber 53. The valve stem 54 is main tained in engagement with the seat 55, by means of a spring 56, and to maintain said valve open, the upper end of its stem is provided with a pivoted member 57, which is adapted to be rocked at right angles to the position shown in Fig. 5 for maintaining the lower end of the valve stem 54 out of engagement with the seat 55 as shown by dotted lines in Fig. 5.

When the valve stem 54 is disengaged from the valve seat 55, a flow of water through the passage 52, chamber 53 and outlet 58, is permitted, and said outlet 58 com municates by means of a pipe 59, with the pan 41, as designated by the reference character 42 hereinbefore mentioned.

By this construction, it will be seen that water is fed automatically to the pan 41 when the Valve 54 is open. The valve 47 is provided with a strainer 60, by means of which impurities in the water are prevented from entering the tank 45, and said tank 45 is further provided with a removable cover 61, whereby access to the interior of the tank may begained.

The operation of the device is as follows: The several baskets 17 are filled with rolls or like articles to be heated, and are placed upon the angle irons 16 within the receptacle 10. The valve stem 54 is now positioned to permit of a flowof water from the tank 45 to the pan 41. The switch 38 is operated and current is permitted to flow to the heaters 36. As the interior of the receptacle 10 becomes heated, it will be seen that the rolls will be subjected to said heat, and owing to its position adjacent one of the heaters 36, evaporation of the water con tained' in the pan 41 is set up to provide the necessary moisture to prevent the rolls drying out under the heating process.

Vhen it is desired to remove the rolls, it is only necessary to exert pressure upon the forward end 34' of the lever 32, and the doors will be operated in the manner heretofore described.

In Fig. 8, the switch 38 is shown as provided on its stem with a cam'member 60'. This cam member 60' is provided with a plurality of peripheral notches 62 in which the upper end of the valve stem 54 may project under the influence of thespring 56 shown.

By such an arrangement it will be apparent that as the electric current is turned on, the flow of water is automatically started to supply the moistening pan 41.

I claim 1. A device of the character described comprising a cabinet, a heating medium for said cabinet,means for controlling the heat to said heating medium, moistening pans for said cabinet, means for supplying water to said moistening pans, and means for automatically controlling the supply of water to the moistening pans, said means being controlled by the heat-contr0lling means, substantially as described.
